the cheapest way to save the earth

i was reading an article by MP Dunleavey called "the cheapest way to save the earth" and here is an excerpt from it...

Not only will greening your lifestyle save you some money, it could even make you a fortune, according to money guru David Bach in his new book, "Go Green, Live Rich."
The subtitle is "50 Simple Ways to Save the Earth and Get Rich Trying," and Bach does deliver some excellent tips. Some of my favorites:
Save $500 a year by not drinking bottled water -- and spare our landfills and oceans a deluge of plastic.
Save $1,400 a year by opting out of junk mail and catalogs -- and shopping less. Bach asserts that Americans get 40 pounds of catalogs per person each year. That's a lot of trees and way too much financial temptation.
"Green bag" your lunch instead of eating out, and save $5-$10 a day and 12 million plastic salad trays (my extremely scientific estimate). Bach says the yearly savings you'll reap by not paying for takeout and all its nonbiodegradable packaging is $2,250.

i guess since Earth Day was April 22nd, i'm all revved up. this is my second day in a row trying to save the world. ha. oh and fyi, today is arbor day...
Happy Arbor Day!
Arbor Day is a nationally-celebrated observance that encourages tree planting and care. :)
